So a couple of my buddys are running Road Atlanta in a Porsche this weekend, the car is using the Bridgestone re71 tires. They plan on using 1 set for the whole 12 or 14 hour race. I know it's a light car, but both of them are used to heavier Corvette/ Mustang platforms and they speak well of those tires. I thought I'd pass that along in case any of you were thinking about buying new rubber. I had another friend recommend them as well, but thought that I'd wait and see before I said anything. Apparently they work well and last a long time, which is what most HPDE guys are looking for.
